DIY 3D Aquarium Decor

Make a decorative structure for your fish tank! Cut and glue pieces of Styrofoam into the shape of your structure, cut a fiberglass cloth into strips and coat the structure with the cloth and resin. Cut away the Styrofoam once the fiberglass has dried, paint the aquarium decoration as desired and coat the structure in more fiberglass resin. Sand the structure for a matte appearance and silicone the structure to the wall of your fish tank.
